Police said two men were seen loitering around the outside of the store at 51st Street and West Oklahoma Avenue overnight just before the fire started at about 11:30 p.m Thursday.

The video shows two people, who police believed to be men, seemingly casing the store, which was closed at the time, peering in the windows and then later turning around and walking back towards the entrance.

In the final frame, it appears that a glow can be seen outside the front doors. In another angle, the pair can be seen knocking something over, and then running off.

Anyone with information about the identity of the men in the surveillance video are asked to call Milwaukee police at 414-935-7360.
